Description
Technical field
The present invention relates to mineral exploration technique field, especially a kind of man-made explosion.
Background technique
In seismology, focus is the initial position that earthquake occurs, and tomography starts the place of rupture, and focus is upwards in the earth
Upright projection on surface is known as earthquake centre.Focus is the place of seismic energy accumulation and release, has a certain size region, also known as
Focal area or focal body.Earthquake is divided into earthquake and artificial earthquake two major classes, and wherein artificial earthquake is caused by human activity
Earthquake, the focus of earthquake caused by human factor claims man-made explosion, and man-made explosion is typically used in seismic prospecting, that is, is utilized
The feature of Underground geologic body is gone in the earthquake that human factor causes.
Man-made explosion is divided into two classes: one kind is dynamite source, and another kind of is non-explosive source.And in seismic survey work
In, for many years focus, wherein effect preferably trinitrotoluene, i.e. TNT explosive, its tool are used as using various explosives always
There are powerful explosions, has a safety feature；Certainly nitrolite can also be used, security performance is more preferable, but other performance ratio
The former is poor.Dynamite source has wide frequency spectrum, is suitable for high frequency (being greater than 80 cycle per seconds), intermediate frequency (15-80 cycle per second), low frequency (6-
15 cycle per seconds) seismic prospecting.The energy of explosive can not largely disappear all on the significant wave required for seismic prospecting
It consumes in keeping surrounding medium broken or formation permanent deformation, part is then as seismic interference.It is especially quick-fried in dry loose rock
When fried, effective energy is lower；The explosion time only in water or aqueous plasticity medium, can just obtain good earthquake effect.
In recent years the non-explosive source occurred just step by step replace dynamite source, the representative of non-explosive source have hammering focus,
Electromagnetic seismic source and spark source.
Hammering focus environmental pollution is small, excitation is controllable, strong interference immunity, can be used according to different detection targets different
Hammer focus.If the non-destructive testing of bridge, workpiece needs dedicated hand hammer, guarantee that the frequency of excitation is sufficiently high, resolution ratio is sufficiently large；
When detection target is the dead zone of several meters to tens meters of underground, unconsolidated formation, need using sledgehammer；When investigation depth reaches hundred meter levels,
When detection target is reservoir, distribution of strata, then need using large-scale pound seismic sources.Although it is wider to hammer focus application range,
It is that it is appropriate only for the occasion not high to resolution requirement, and energy consumption is big, is not particularly suitable in Mountainous Regions as focus
It uses.
Electromagnetic seismic source is generally made of control cabinet and jump bit two parts, is a kind of pulse shock focus, be can be used for 100 meters
Within shallow seismic exploration, especially hard surfacing.The wave frequency rate of electromagnetic seismic source excitation is abundant, not damaged road surface, does not have to beat
Hole, for hammering focus, cost is slightly higher, and transport it is convenient not as good as sledgehammer, be relatively suitable for urban pavement empty detection,
The fields such as pipeline detection, Air-raid Shelter Exploration, Metro Line Selection.
Spark source is one kind of electric energy focus, is to be added to the electric energy stored using capacitor to be pre-placed in water
In electrode on, in extremely short moment (Microsecond grade) release high-voltage electricity (discharging), up to ten thousand degrees Celsius of electric arc is formed, by steam
Change, generates percussive pressure Reeb；But spark source can only use in water.
Above-mentioned non-explosive source all has some limitations, and is unable to satisfy the requirement of seismic survey.
